Energy Use Index

Energy Use Index (EUI): Total energy (electricity, natural gas and imported steam)
consumed by Texas Tech University (all facilities in Texas owned by TTU) expressed
as thousands of British Thermal Units (BTUs) divided by the Occupied Square Foot conditioned
spaces only. All energy, interior and exterior, is aggregated in the numerator, but
the square footage of only the occupied spaces are counted in the denominator. The
solid black line represents TTU's long term Energy Use Index goal of 117. The green
column represents the goal for FY15.
